[0026] The ventilation assembly 3 includes a motor 31 installed on the top of the tower body 1, a fan blade 32 is provided on the output side of the motor 31 near the inner end of the tower body 1, an exhaust pipe 33 is provided on both sides of the top of the tower body 1 near the motor 31, and a plurality of groups of air replenishing holes with embedded filter blocks are provided in the tower body 1 near the lower edge of the spiral tube assembly 2; a discharge pipe is installed on the side of the second three-way valve 44 away from the tower body 1, and the water pumping pipe 43 and the discharge pipe are connected to the external water source, and a temperature sensor and a liquid level sensor are respectively provided on the inside of the tower body 1; through the water pump 41, the first three-way valve 42, the water pumping pipe 43, the second three-way valve 44, the conduit 45, the spray frame 46, the temperature sensor, and the liquid level sensor cooperate with each other, so that the device can introduce and recycle the water for spraying and heat dissipation according to needs, and after use, the water accumulated at the bottom of the tower body 1 can be promptly discharged for subsequent cleaning;

[0027] like Figure 1-2 The second embodiment shown is mainly different from the first embodiment in that:

[0028] The heat sink 5 includes two sets of first solenoid valves 51 arranged on the side of the tower body 1. A temporary storage shell 52 is installed at the end of the first solenoid valve 51 away from the tower body 1. A plurality of heat sinks 53 are arranged on the outer side of the temporary storage shell 52. A second solenoid valve 54 is installed on the lower edge of the temporary storage shell 52.

[0029] The first solenoid valve 51 is located at the upper edge of the temporary storage shell 52, and the second solenoid valve 54 is installed with a reflux pipe away from the temporary storage shell 52. The two groups of temporary storage shells 52 are both provided with auxiliary temperature sensors and auxiliary liquid level sensors. The liquid level sensor and the temperature sensor respectively measure the liquid level of the accumulated water on the lower side of the tower body 1. When the water level reaches a critical value and the water temperature exceeds the circulatory cooling range, the first solenoid valve 51 on one side of the tower body 1 is opened, and the water at the bottom of the tower body 1 flows into the temporary storage shell 52 at this location through the first solenoid valve 51 at this location. The heat sink 53 on the outer side of the temporary storage shell 52 dissipates the water in the temporary storage shell 52 through heat transfer. When the water in the temporary storage shell 52 reaches a specified liquid level, the first solenoid valve 51 here is closed, and the first solenoid valve 51 on the other side is opened, and the liquid level temporary storage and heat dissipation operations are repeated. After the auxiliary temperature sensor detects that the water in the temporary storage shell 52 drops to a suitable range, the second solenoid valve 54 is opened, and the water that has been cooled flows back to the water source through the reflux pipe.

[0030] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited, and conventional equipment can be used.

[0031] During use, the user starts the motor 31 and the water pump 41, and the motor 31 drives the fan blades 32 to rotate. The fan blades 32 introduce the outside air through the filter block and discharge it through the spiral tube assembly 2, the fan blades 32, and the exhaust pipe 33. The water pump 41 draws cold water from the outside water source through the first three-way valve 42 and the water pumping pipe 43, and the water is sprayed out through the second three-way valve 44, the conduit 45, the spray frame 46, and the spray column. The water sprayed by the spray column sprays the middle part of the spiral tube 22, and the spray water falls on the bottom of the tower body 1. At the same time, the liquid to be cooled is introduced into the spiral tube 22 through the liquid inlet pipe and the liquid inlet ring 21. The water sprayed by the spray column performs heat exchange treatment on the liquid passing through the spiral tube 22 through heat exchange, and the airflow generated by the fan blades 32 extracts the heat in the spray water, thereby improving the heat dissipation efficiency. In the above process In the process, the liquid level sensor and the temperature sensor respectively measure the liquid level of the accumulated water on the lower side of the tower body 1. When the water level reaches the critical value and the temperature is in the circulatory cooling range, the first three-way valve 42 is reversed. At this time, the water pump 41 changes to pump water from the bottom of the tower body 1 to achieve circulatory cooling of the water. When the water temperature at the bottom of the tower body 1 exceeds the circulatory cooling range, the first three-way valve 42 is reset and the first solenoid valve 51 on one side of the tower body 1 is opened. At this time, the water pump 41 continues to pump water from the outside, and the water at the bottom of the tower body 1 flows into the temporary storage shell 52 at this location through the first solenoid valve 51 at this location. The heat sink 53 on the outer side of the temporary storage shell 52 dissipates the water in the temporary storage shell 52 through heat transfer. After the water in the temporary storage shell 52 reaches the specified liquid level, the first solenoid valve 51 here is closed, and the first solenoid valve 51 on the other side is opened.
